Message Card Size: 5.5cm (height) x 9cm (width) Washi paper is used for the area to write your message. Different Yuzen washi paper is pasted on both sides, creating a high-quality message card (⁠•⁠‿⁠•⁠) The Yuzen washi paper is placed on the sides because if it were placed on the top and bottom, the area for writing the message would be reduced. Since the remaining Yuzen washi paper from various uses is used, the width of the Yuzen washi paper is not the same. It will be protected from water damage and sent in an envelope. I would like to do business with those who can provide some comments after purchase.
